` Application ledlllay 10,1900. Serial No. 16,172. (No model.)

To cir/ZZ whom it Iii/ty concern.-

Beit known that I, FREDERICK W. NUREN- BERG, a citizen of the United States, residing at the city of New York, borough of Brooklyn,

county of Kings, and State of New York, have invented certain new and useful Improvements in Copying-Presses, of which the following is a specification.

My invention has for its object the improvexo ment and simplification of devices employed for letter-press copying and the like and the material reduction in the cost and maintenance thereof. y

In letter-press copying devices of the ad- :5 vanced type wringers or rotary rollers comprising wringing devices are employed whereby copying-pads may be compressed to deprive them of superfluous moisture. These wringing devices have been used in two ways,

zo known in the art to which this invention relates as that of the old style and that of the new style. In the old-style presses having wringing devices there is provided a pan adapted to contain water, the pan being so located relatively to the lower roller of the wringer that it will carry the water from the pan onto the pad as the latter is beingpassed through the wringers, simultaneously moistening the pad andpressing out the supergo iluous moisture therefrom, In this class of devices in order to free the water-pan from the frame of the machine for replenishment, cleansing, or for any other purpose or to introduce the pan under the rollers so that the lowermost roller will lie below the waterlevel the rollers were mounted in a swinging frame, which was adapted to permit the lowermo'st roller to be swung upwardly clear of the top ot' the pan, so as to allow the pan being moved 4o out or in, as occasion demanded, by sliding it on a horizontal plane transversely of the frame, and when the pan was in position it was locked and the lower roller swung to its position within the pan. The class of copy- .15' ing-presses denominated new style have the general characteristics of the above, eX- cept that the pan is not so located in the frame of Vt-he press that the vlower roller will lie below the water-level, but is removed 5o therefrom, so as to allow the rollers to act merely as wringers and not as water-feeders- In using these latter devices the copying-pads are kept in the water in the pan for a considerable length of time, and when sufficiently impregnated they are removed from the pan and passed through the rollers, then acting as wringers, thus relieving the pads of super:- Iluous moisture, the pads then being placed in a suitable receptacle and stored away for ready use. Each of these classes of presses 6o is desirable for use under certain condi tions, and it is not usual that the conditions are such as to require that both classes of machines be used in thesame place-that is to say, where a large amount of copying is to be done it has been found expedient to employ the new style, with which a large number of pads can be soaked and wrung outand stored away ready for use, while under other conditions, where a comparatively small 7o amount of copying is to be done, it is found sufficient to wet and wring the pads at the same time-namely, in accordance with the old style. Copying-presses are therefore made where wringing attachments are provided either in the new style or old style forms, being both separate and distinct machines.

The copyingprcss made in accordance with myinvention embodies means whereby it can So be transformed at once without alteration of the parts from the new style into the old style, or vice versa, in a simple and expeditious manner. y

Another important consideration in the construction of devices of this kind is their adaptability to ready repair, it very often occurring that parts of these machines become broken in use and necessitate repairing of the parts. My improved press is organized for 9o the purpose of permitting ready repair in all of its parts, and more particularly the wringing portion thereof, wherein the rollers, the supporting-shafts, journal box or bearings, tension devices, and operating-handle are made bodily detachable' from or attachable to the frame of the machine without disturbing any of these parts.

In order to provide for the expeditious change from old and new style 1nacl1ine,means roo are provided whereby the water-pan may be superposed over the press portion of the apparatus, also means whereby the pan may be expeditiously raised or lowered to or from the wringer-rolls, and, further, means for allowing the ready attachment or detachment of the pan to or from the said raising or lowering means.

My invention further relates tothe support of the rollers in the bearing-blocks and the means for connecting the same to the frame of the machine; further, to the ltension devices for the rollers and to the general coustruction of the frame of the machine, in which the uprights for supporting the wringer and pan, the arch, and the legs are all made integral; further, to a stripping device for the copying-pads, which latter are carried by and adjustable coincidently with the lowermost or adjustable roller of the wringer, so as to at all times bear the proper relationship to the bight between the rollers, enabling the pad to be properl7 stripped for the rollers.

My invention therefore resides in the construction and combination of parts hereinafter described, and further pointed out in the claims.

In the drawings forming part of this speciiication, Figure 1 is a side elevation of a copying-press embodying my improvements, the pan being arranged to constitute a new-style press. Fig. 2 is a sectional elevation on the line A A, Fig. 1, looking in the direction of the arrow. Fig. 3 is a sectional elevation longitudinally on the line fr, Fig. 4, and enlarged, showing the upper portion of one of the main-frame arms, the bearingblock, roller-yoke, tension device, and a portion of the wringers. Fig.A 4 is a transverse sectional elevation of the saine substantially on the line z z, Fig. 3. Fig. 5 is an inverted plan view of the bottom of the pan, its supporting-spider, and operating-wheel. Fig. 6

t is a side elevation of the saine, partly in sec'- tion. Fig. 7 isa perspective View of the pan. Fig. 8 is an enlarged perspective elevation of one of the bearing-blocks. Fig. 9 is a like view of one of the roller-yokes, and Fig. 10 is a side elevation of the upper portion of one of the main-frame arms.

Similar numerals of reference indicate corresponding parts throughout the several views.

The frame of the machine is constructed as follows:

1 is the arch or cross-piece, having a central enlargement or boss 2, as indicated in cross-section, Fig. 2, so as to provide great strength to resist vertical strain, which arch is formed integrally with the uprights 3, and an interior or vertical rib 4, forming a guide for the platen 5, which rib merges into a gradually-deepening rib 6, owing into the boss 2. The top of the arch is flat, as at 7, and of equal thickness with the uprights 3 at the transverse center, as shown in Fig. 2.

At 8 are the arms of the wringer-frame, extending upwardly from the arch l, preferably within the line of the uprights 3, which arms are provided with square recesses 9 between the extensions 10 at the upper ends to receive the bearingblocks and which are formed with grooves 11 (see Fig. 2) in their inner faces to form guides for the projecting arms of the pan-spider, hereinafter to be described. A strengthening-web 12 connects the uprights, arch, and arms 8.

The boss 2 of the arch is provided with a bore 1 2, the lower section 13 of which is interiorly threaded to receive the thread of the double-acting screw-spindle 14, having the two screws 15 16 working in opposite directions, right and left hand, its intermediate portions 14 passing through the hub 17 of the hand-wheel 18, the latter being secured to the spindle by the pin 19 passing diagonally therethrough, as indicated in Fig. 2, the lower thread 16 of the spindle engaging the bored and threaded boss 2O of the platen 5, which latter has the bifurcated lugs 2l embracing the rib 4 on the uprights 3, whereby the platen is guided in its movements up and down when operated by the hand-wheel and spindle.

At 22 is the base to which the uprights are secured by bolts 23, (indicated in dotted lines in Fig. 1,) the base 22 comprising the crown 24, the side walls 25, and the front opening 26 for the reception of the pad-tray hereinafter described, the side walls being partly vertical and partly inclined.

To strengthen the crown of the base, it is provided with ribs 27 28, formed integrally therewith and extending transversely and longitudinally and across each other, asindicated in Fig. 2.

At 29 30 are the pressure-rollers, mounted upon shafts 31 32, the upper roller29 and its shaft being mounted in xed bearings 33 34 in a bearing-block the lower roller and its shaft 32 being mounted in a bearing, forming a cross-head 36 of a yoke 37, having the side pieces 3S and top cross-bar 39, the side pieces forming a slot 40, through which the shaft 3l of the upper roller passes, the yoke and its hereinafter-described adjuncts forming means for adjusting the tension of the rollers in respect to each other, and which yoke, although movable within the recess 41, formed in the bearing-block -35, is portable with it. The yoke at the cross-head 36 is solid and engages the side pieces 42 43 of the block. rlhe inner wall of the bearing is slotted (44) or open at the lower portion to allow of the cross-head of the yoke to extend therethrough, Fig. 3, and above the slotted openings of the blocks the inner and outer walls 45 46 are provided with the apertures 33 34, through which the shaft 31 passes and which provide bearings for said shaft.

At 47 is a plate or follower extending between the side pieces 3S of the yoke and squared so as to prevent its rotation, the follower having the threaded portion of the stem 48 of a screw passing therethrough, the stem also passing through the cross-bar 39 and IOC , the bearing in position.

through an aperture in the top plate 49 of the bearing-block, the head 50 ot' the screw resting upon the top plate of the block.

Between the follower and the cross'bar of the yoke extends a spring 5l, which also surrounds the stem 4:8 of the adjunctive screw.

Through the medium of the foregoing instrumentalities a housing is provided for the ends of the shafts and for the yoke which carries the lower roll, the movement of the lower roll up and down is guided, the separation of the rolls is resiliently opposed, and the adjustment of the tension of the rollers through the adjustingscrew, which adjusting means is separable from eachv end of the roll and each independently of the other, except as the two may be connected by the roller itself, and such adjusting means is retained within the housing, so as to prevent its being interfered with.

By means of the foregoing constructions both rollers, with their bearings, are maintained together as a unit, by reason of which the rolls and the bearings can be readily un.- shipped from the frame for repair or replacement or separation from each other without dismembering the bearings or the rolls, and the same unit can be expeditiously attached to the frame and set in position. To provide for this latter feature, the face 46 of the bearing-block is provided with an outwardly-extending lug 52, from which depends an outwardly-extending squared boss 53, of less diameter than the shoulder, the aperture 33, forming the bearing for the end of the shaft 3l in the outer portion of the block, extending through this boss. The upper ends ofthe side arms S are bifurcated, as shown in Fig. lO, forming the slot 9, in which the squared boss 53 is'received, as indicated in Fig. 3, the extensions l0 bearing against the sides of the boss and the lower port-ion of the boss resting upon the solid portion 54 of the side arms, as indicated in Fig. 3, the outer wall 46 ofthe bearing-block having a depending flange 55 extending below the bottom of the slot and bearing against the inside of the arm, the shoulders 56 of the lug resting on the top of the extensions, and interlocking union of the blocks and arms is provided, the bearing blocks iirmly seated, and movement downwardly longitudinally or transversely prevented. A screw 57, Figs. 2 and 4, passing through theinner extension l0, firmly secures Another valuable feature secured by this construction is that by reason of the fact that the bearinglblocks are made separate from each other-that is, unconnected above the rollers-the space above the roller is left free and clear.

In prior constructions where the frame is connected by a bar lying above the rollers the copying-pads in passing through the rollers would very often strike the rear of the cross-bar and curl up, and very often when the operator reached over to secure the end is provided with a two-part cover, the front 59, having a recess GO in its inner edge and which is detachable, the rear parts 61 being fixed to the sides 61a of the pan, leaving a central opening 62 for the passage ofthe lower roller into the water-space of the pan, slidable transversely in relation to the rollers, I have provided means for raising or lowering the pan to or from the rollers, thereby avoiding the complicated structure involved in the means for pivotally swinging the rollers transversely, my in'lprovements permitting of the pan being raised to bring the lower roller below the water-level or the water-level removed therefrom, so that the roller may be used alternately for either old or new style copying, as previously described, without change in the apparatus-that is, either as a wringer alone or as a combined moistener and wringer. The construction is as follows: At 63 is a frame or spider (shown in plan in Fig. 5) having a central hub 64, which iixedly receives the upper end of the screw-rod 65, from which hub radiate the lateral supportingarms 66, and from which hub also extend the longitudinal arms 67,(foextensive with the distance between the side arms S of the main frame, the longitudinal arms 67 having pendent lugs 68, which engage the grooves ll in side arms, as indicated in Fig. l, to form guides for the up-anddown movements ot' the spider and pan and restraining horizontal vibration. The lower end of the screw-rod is guided in a thimble 6H, tixed in the bore 12 of the arch-boss 2, the t-himble being wholly or partly provided with an internal bore 70 to allow of the la'tters free movement up and down. At 7l is a hand-wheel provided with an enlarged hub 72, resting on the arch-boss, Fig. 2, and through which the screwrod passes. It will be clear that as the hand- Wheel is rotated in either direction, so the spider will be moved upwardly or downwardly between the side arms 8 oi frame. 'lhe longitudinal arms of the spiderare provided with bosses 73, having open-ended slots 74, and extending from the bottom of the pan are threaded studs 75, which pass through the slots of the bosses. Nuts 76, movable upon the studs and bearing against the lugs, `[irmly secure the pan to the spider, permitting it to be readily attached or detached and causing it to be coincidently movable with the spider. To attach or detach the pan to the spider, the latter is lowered so as to leave su fiicient clearance below the lower roller for the insertion or removal of the pan, when the `latter may either be attached or detached by loosening the nuts and passing the studs through the IOO ICS

IIS

slots in the lugs. The sides 42 I3 of the bearing-bloc' s are cut away to provide a clearance for the sides 6 1 of the pan when raised, Fig. 2, as shown at 77, Fig. l.

In previous devices of this class means have been provided for stripping (as it is called) the pad from the rollers, so as to prevent the pad from following the rollers around and becoming curled upon it. In said prior constructions the stripper has been secured to the pan or to some other part of the device entirelyT independent of either of the rollers, which has resulted in complicating the device and rendering its use more difficult and uncertain. My improvements contemplate carrying the stripper by a part coincidently movable perpendicularly with the lower roller, so that at all periods of adjustment ot' said roller the stripper will maintain its operative relationship thereto. To this end I have provided the arms 78, which are cast integrally with or otherwise secured to the cross-head 36, one end of which is formed with an apertured eye 79, through which passes the lower shaft 32 and which lies close to the face of the crosshead of the yoke 37, the outer end 8O of the arm extending beyond the sides of the yoke and through a recess 8l, cut in the sides 4:2 of the block and provided with an offset 82, in which is a screw-hole 83, as shown in Fig. 9, upon which the central flat portion 84 of the stripper is secured by the screw 85, passing through it into the hole 83, the portion 84 being cut away at the ends to allow of its being located at the side of the block-bearing, Fig. 4, the stripper-plate having an inwardly-extending edge 86, Fig. 2, located over and in close proximity to the periphery of the lower roll 30 and within the bight of both rollers, the outer portion of the stripper being eX* tended upwardly at S7 to form a guide-plate for the copying-pad, at its exit from the roll, so as to direct its movement upwardly and over the top roll. As the stripper-plate is maintained in a fixed relation to the lower adjustable roller, its coperative relationship with the roller during all of its periods of adjustment is positively maintained.

At 88 is the pad-drawer, preferably formed with bottom, sides, and ends of metal and a front bar 89 of wood covered with sheet metal 90 for finishing, between which and the front piece 91 is inserted a plate 92, thereby making a light and strong drawer, the bar 89 strengthening the thin front. The pan rests on a shelf 93, having a rear stop-piece 94, secured within the recess 95 in the base of the frame. The bar S9 has a pull `96.
